Functions | |
| TangoErrorType | TangoSupport_calculateRelativePose (double base_timestamp, TangoCoordinateFrameType base_frame, double target_timestamp, TangoCoordinateFrameType target_frame, TangoPoseData *base_frame_T_target_frame) |
| Calculates the relative pose of the target frame at time target_timestamp with respect to the base frame at time base_timestamp. More... | |
| TangoErrorType | TangoSupport_createImageBufferManager (TangoImageFormatType format, int width, int height, TangoSupport_ImageBufferManager **manager) |
| Create an object for maintaining a set of image buffers for a specified image format and size. More... | |
| TangoErrorType | TangoSupport_createPointCloudManager (size_t max_points, TangoSupport_PointCloudManager **manager) |
| Create an object for maintaining a set of point clouds for a specified size. More... | |
| TangoErrorType | TangoSupport_fitMultiplePlaneModelsNearPoint (const TangoPointCloud *point_cloud, const double point_cloud_translation[3], const double point_cloud_orientation[4], const float color_camera_uv_coordinates[2], TangoSupport_Rotation display_rotation, const double color_camera_translation[3], const double color_camera_orientation[4], TangoSupport_Plane **planes, int *number_of_planes) |
| Similar to TangoSupport_fitPlaneModelNearPoint, but after finding a plane at the user selection, points fitting the fit plane are removed from the input points to the RANSAC step and the process is repeated until a fit plane is not found. The output planes are in the base frame of the input translations and rotations. This output frame is usually an application's world frame. Unlike the single plane version, the planes need to be freed by calling TangoSupport_freePlaneList. More... | |
| TangoErrorType | TangoSupport_fitPlaneModelNearPoint (const TangoPointCloud *point_cloud, const double point_cloud_translation[3], const double point_cloud_orientation[4], const float color_camera_uv_coordinates[2], TangoSupport_Rotation display_rotation, const double color_camera_translation[3], const double color_camera_orientation[4], double intersection_point[3], double plane_model[4]) |
| Fits a plane to a point cloud near a user-specified location. This occurs in two passes. First, all points are projected to the image plane and only points near the user selection are kept. Then a plane is fit to the subset using RANSAC. After the RANSAC fit, all inliers from a larger subset of the original input point cloud are used to refine the plane model. The output is in the base frame of the input translations and rotations. This output frame is usually an application's world frame. More... | |
| TangoErrorType | TangoSupport_freeImageBufferManager (TangoSupport_ImageBufferManager *manager) |
| Delete the image buffer manager object. More... | |
| void | TangoSupport_freePlaneList (TangoSupport_Plane **planes) |

| TangoErrorType | TangoSupport_freePointCloudManager (TangoSupport_PointCloudManager *manager) |
| Delete the point cloud manager object. More... | |

| TangoErrorType | TangoSupport_getCameraIntrinsicsBasedOnDisplayRotation (TangoCameraId camera_id, TangoSupport_Rotation display_rotation, TangoCameraIntrinsics *intrinsics) |

| TangoErrorType | TangoSupport_getDoubleMatrixTransformAtTime (double timestamp, TangoCoordinateFrameType base_frame, TangoCoordinateFrameType target_frame, TangoSupport_EngineType base_engine, TangoSupport_EngineType target_engine, TangoSupport_Rotation display_rotation, TangoSupport_DoubleMatrixTransformData *matrix_transform) |
| Calculate the tranformation matrix between specified frames and engine types. The output matrix uses doubles and is in column-major order. More... | |
| TangoErrorType | TangoSupport_getLatestImageBuffer (TangoSupport_ImageBufferManager *manager, TangoImageBuffer **image_buffer) |
| Check if updated color image data is available. If so, swap new data to the front buffer and set image_buffer to point to the front buffer. Multiple calls to this function must be made from the same thread. More... | |
| TangoErrorType | TangoSupport_getLatestImageBufferAndNewDataFlag (TangoSupport_ImageBufferManager *manager, TangoImageBuffer **image_buffer, bool *new_data) |
| Check if updated color image data is available. If so, swap new data to the front buffer and set image_buffer to point to the front buffer. Multiple calls to this function must be made from the same thread. Set new_data to true when image_buffer points to new data. More... | |
| TangoErrorType | TangoSupport_getLatestPointCloud (TangoSupport_PointCloudManager *manager, TangoPointCloud **latest_point_cloud) |
| Check if updated point cloud data is available. If so, swap new data to the front buffer and set latest_point_cloud to point to the front buffer. Multiple calls to this function must be made from the same thread. More... | |
| TangoErrorType | TangoSupport_getLatestPointCloudAndNewDataFlag (TangoSupport_PointCloudManager *manager, TangoPointCloud **latest_point_cloud, bool *new_data) |
Check if updated point cloud data is available. If so, swap new data to the front buffer and set latest_point_cloud to point to the front buffer. Multiple calls to this function must be made from the same thread. Set new_data to true if latest_point_cloud points to new point cloud. More... | |
| TangoErrorType | TangoSupport_getLatestPointCloudWithPose (TangoSupport_PointCloudManager *manager, TangoCoordinateFrameType base_frame, TangoSupport_EngineType base_engine, TangoSupport_EngineType target_engine, TangoSupport_Rotation display_rotation, TangoPointCloud **latest_point_cloud, TangoPoseData *pose) |
| Returns the latest point cloud that has a pose. There is no target frame parameter because only FRAME_CAMERA_DEPTH has meaningful semantics for point clouds. Assumes the same base_engine and target_engine will be passed in each time. More... | |
| TangoErrorType | TangoSupport_getMatrixTransformAtTime (double timestamp, TangoCoordinateFrameType base_frame, TangoCoordinateFrameType target_frame, TangoSupport_EngineType base_engine, TangoSupport_EngineType target_engine, TangoSupport_Rotation display_rotation, TangoSupport_MatrixTransformData *matrix_transform) |

| Get a pose at a given timestamp from the base to the target frame using the specified target and base engine's coordinate system conventions. The base and target engine must either both be right-handed systems or both be left-handed systems. More... | |
| TangoErrorType | TangoSupport_getTangoVersion (void *jni_env, void *activity, int *version) |
| Get the version code of the installed TangoCore package. More... | |
| TangoErrorType | TangoSupport_getVideoOverlayUVBasedOnDisplayRotation (const float uv_coordinates[8], TangoSupport_Rotation display_rotation, float output_uv_coordinates[8]) |
| Get the video overlay UV coordinates based on the display rotation. Given the UV coordinates belonging to a display rotation that matches the camera rotation, this function will return the UV coordinates for any display rotation. More... | |
| void | TangoSupport_initialize (TangoSupport_GetPoseAtTimeFn getPoseAtTime, TangoSupport_GetCameraIntrinsicsFn getCameraIntrinsics) |
| Initialize the support library with function pointers required by the library. NOTE: This function must be called after the Android service has been bound. More... | |
| bool | TangoSupport_isValidRotation (TangoSupport_Rotation rotation, bool allowIgnored) |
| Indicates whether a given rotation is valid or not. More... | |
| TangoErrorType | TangoSupport_setImageBufferCopyRegion (TangoSupport_ImageBufferManager *manager, int y_only, uint32_t begin_line, uint32_t end_line) |
| Limit copying of the incoming image to a specific range of scan lines. More... | |
| TangoErrorType | TangoSupport_updateImageBuffer (TangoSupport_ImageBufferManager *manager, const TangoImageBuffer *image_buffer) |
| Updates the back buffer of the manager with new data from the callback. This should be called from the image callback thread. More... | |
| TangoErrorType | TangoSupport_updatePointCloud (TangoSupport_PointCloudManager *manager, const TangoPointCloud *point_cloud) |
| Updates the back buffer of the manager. Can be safely called from the callback thread. Update is skipped if point cloud is empty. More... | |
